No

Error:
SIM card is detected
(1) no connection
(2) 30s reaction time to any single user click

Environment:
lenovo X200 with build-in WAN (Ericsson F3507g, currently not supported afaik), no SIM card inserted
USB stick with HUAWEI Mobile
linux kernel 28.6.28
kde 3.5

What I did:
looked up the ttys associated to the same USB device as the HUAWEI controller: "dmesg | grep HUA" -> USB 4-1, "dmesg | grep 4-1" -> ttyUSB5,ttyUSB6.
started umtsmon with "sudo umtsmon -s ttyUSB5,ttyUSB6", entered the PIN, a network is found, however, connetion timed out.
Now, umtsmon is left nearly unusable. Any state change in the user interface takes 30s. Programming error in error processing?

Workaround:
Fortunately the x200 comes with a switch to disable Bluetooth, WLAN and WWAN. I got to re-boot with the disable switch activated. HUAWEI is found on ttyUSB0 and 1., network is found and I'm able to connect to it - the system is working.

Note:
As I do have a workaround, this issue is meant to improve error handling of umtsmon.
